Specification of Letters Patent No. 28,708, dated June 12, 1860.

To all whom t may concern:

Be it known that we, SELIM E. WOOD- WORTH and JAMES S. WETHERED, of the city and county of San Francisco and State of Y California, have invented a new and Im proved Gas Burner, which we call Woodworth and IVethereds Aeriolame Gashole through it as represented at e, with a hole it, perpendicular to, and connecting with the same. It will be perceived that the gas passing in the direction of the arrows, is emitted at the openings c, c. The atmospheric air passing in at the openings e, c,

escapes at L, and is mixed with the gas, supplying oxygen, thereby increasing the illuminating power.

le do not claim the mixture of atmospheric air with illuminating gas, for the purpose of increasing its illuminating power.

That we claim and for which we desire Letters Patent to issue, is-

The introduction of atmospheric air into the center of the gas llame, in manner substantially as described, and for the uses and purposes herein set forth.
